The dispensing column is cooled with the aid of a cooling liquid which is introduced into the dispensing column via an inlet in a chamber and which is discharged out of the chamber via an outlet. The cooling liquid is cooled in a second heat exchanger, which is integrated with the first heat exchanger in one block. A beverage line extends from the container to a tap and is in thermal contact with the beverage line because the beverage line is pressed against a wall of the chamber. During use, the air to be cooled and the coolant exchange heat with the same cooling element.

With this known tapping device, the beverage line is pressed against a wall of the chamber cooled by the cooling liquid, so that direct thermal contact is obtained. The tap column is separated from the first cooling medium. The temperature of the tapping column will thereby have to be brought and kept approximately at the desired tapping temperature of the beverage by the cooling liquid, in order to be able to dispense the beverage with that desired temperature and to prevent freezing of the beverage in the beverage line. The temperature of the cooling liquid must hereby be controlled within narrow limits and, moreover, must be kept relatively high.

An object of the present invention is to provide a dispensing column and tapping device, wherein the temperature of the dispensing column can be controlled, substantially independent of the temperature of the beverage present in a dispensing line in the dispensing column.

Another object of the present invention is to provide a dispensing column, the temperature of which can be adjusted, such that the outside thereof is colder than the desired temperature of the beverage to be dispensed.

A further object of the present invention is to provide a dispensing column on which ice can be formed on the outside, also in a relatively warm space, while the beverage present in a beverage line in the dispensing column remains liquid.

Another object of the invention is to provide a method for controlling the temperature of a beverage in a beverage line extending through a dispensing column.

Also embodiments which do not eliminate the disadvantages or not all the disadvantages of the prior art, or which do not attain the advantages or not all the advantages which are intended, can fall under the invention claimed by the claims.

FIG. 1 shows a tapping device 1 in the built-in state. FIG. 2 shows a tapping device 1 that can be used for this purpose. The tapping device 1 comprises a cooling device 2 with two tapping columns 3 on it in the exemplary embodiment shown. For example, the right tapping column 3A can be an extra cooled tapping column, for example an ice column (iced countermount) and the left tapping column 3B a normal cooled tapping column. cooled tap column (cooled countermount). The tapping columns 3 can be carried directly on a top side of the cooling device 2, but can also, for example, with a built-in cooling device 2, at least partially rest on a tapping plate 4 such as a bar. In the cooling device, a beverage container 5 (Fig. 3) such as a beer cask, wine barrel or the like, or several, the same or different, containers 5 can be arranged, which are connected via one or more beverage lines 6 to one or more of the dispensing columns 3 or arranged thereon taps 7 can be connected. As a result, beverage can be dispensed from the beverage containers 5 with the aid of the taps 7. In this description, extra cooled tap column is to be understood at least but not exclusively to be a tap column 3 of which at least a part is cooled, in particular to below the freezing point of water and / or condensation. In one embodiment, the cooled tap column can be cooled such that during use an ice layer is formed over virtually the entire outer surface thereof. In another embodiment, only a portion of the tapping column 3 or a portion of an outer surface 8 thereof can be cooled to form an ice layer. If several tapping columns 3 are used, extra cooling must be understood to mean at least but not exclusively a tapping column 3 which is cooled to a lower temperature than the other, normal tapping column 3, based on the lowest outside temperature thereof.

In a tapping device 1 according to this description, preferably two heat exchangers are used, as schematically shown in Fig. 3. A first heat exchanger 9 is provided for cooling a cooling space 10 in which the containers 5 are or can be arranged. A second heat exchanger 11 is provided with which at least the first, extra cooled tap column 3A can be cooled. The first and second heat exchangers 9, 11 can use the same cooling medium, such as air. In the exemplary embodiment shown in Fig. 3, air is cooled with the first heat exchanger 9, with the second heat exchanger 11 a liquid, for example glycol or a liquid containing glycol. A different temperature can preferably be controlled with the second heat exchanger 11 than with the first heat exchanger 9, preferably a lower one. In the embodiments shown, the first heat exchanger 9 is a finned heat exchanger, the second heat exchanger 11 a tube-in-tube type (tube-in-tube) heat exchanger. However, other types of heat exchangers can also be used as first and / or second heat exchangers 9, 11.

In the embodiment shown in Fig. 3, one tapping column 3 is shown, which can be designed as an additional cooled tapping column 3A or can be operated as such. The tapping column 3 comprises a casing 13, a supply 14 and a discharge 15. A passage 16 is provided within the casing 13, which extends between an inlet 17 and the tap 7. The inlet 17 can be located near a lower end 18 of the casing 13, but the passage 16 can also extend beyond said lower end 18, into the cooling space 10, such that the inlet 17 is provided in the cooling space 10. The passage 16 can be provided with a side inlet 19 through which the beverage line 6 can be introduced into the passage 16, at least during use. However, the beverage line 6 can also be introduced via the inlet 17. The beverage line 6 can be a disposable beverage line which, for example, is replaced when a container 5 is changed or is replaced after a number of containers 5, but can also be provided permanently. Disposable in this context should at least but not exclusively be understood to mean a beverage line which is designed such that it is thrown away after use. To that end, the beverage line can for instance be made relatively inexpensively in plastic, for instance as known from the David® system offered by Heineken®, from the DraftMaster® system offered by Carlsberg®, the SmartDraft® system offered by Micromatic or as described in EP1289874. The beverage line 6 extends through the passage 16 to or in the tap 7. In one embodiment, the tap 7 can be designed as a tap 7 of a known tap column, the beverage line 6 being connected to one end thereof and the tap 7 has its own valve (not shown).

Such an embodiment is particularly suitable when using a (semi) permanent beverage line. In another embodiment, the beverage line 6 can be provided with a valve (not shown) which can be placed in the tap 7 or can cooperate with it, as is known, for example, from the David® system offered by Heineken®, from the system supplied by 7

Carlsberg® offered DraftMaster® system, or the SmartDraft® system offered by Micromatic or as described in EP1289874. In yet another embodiment, the beverage line can be provided with a compressible end 20, which can be squeezed shut by the tap 7 and / or can be opened or whose passage 21 can be released, as is known, for example, from Philips® and InBev ® offered PerfectDraft® system. The systems and patent application mentioned above are given for illustration only and should not be construed as being limitative in any way.

In the embodiment shown in Fig. 3, at least partially a space 24 is provided between a wall 22 of the passage 16 and the outside 23 of the beverage line 6 within the passage 16, which space is in fluid communication with the cooling space via the inlet 17 10. The space 24 can form an air cavity and largely prevent direct contact between pipes and wall 22. The wall 22 can be thermally insulating. Near the inlet 17, a fan 25 can be provided, which can be driven for introducing air from the cooling space 10 into the space 24 and / or sucking air from the space 24 into the cooling space. As a result, the temperature in the space can 24 can be controlled and the space 24 can form a temperature control space. In another embodiment, the fan 25 is omitted and natural or forced convection is used for the passage of air through the tapping column under the influence of pressure differences, which may, for example, result from temperature differences between the cooled space 10 and the surroundings of the tapping device. .

Within the casing 13, around at least a part of the passage 16, in the embodiment shown in Fig. 3, a space 26 is provided, for example a chamber which is in fluid communication with the supply 14 and the output 15. In the embodiment shown in Figs. In the embodiment shown in Fig. 3, the supply 14 is arranged low in the space 26 and the discharge 15 high, so that venting of the space 26 is relatively simple. However, this can also be carried out differently or be dependent on a selected flow direction of the second cooling fluid. The supply 14 is connected via a first conduit 27 which extends through the second heat exchanger 11 to a pressure side of a pump 28. The suction side of the pump 28 is connected via a second conduit 29 to a vessel 30, which vessel 30 is a third line 31 is connected to the outlet 15. The lines 27, 29, 31, the space 26, the pump 28 and the vessel 30 form a second cooling circuit C2 and are filled with the second cooling medium, for example glycol 32, which pump 28 can be pumped around. Between the delivery side of the pump 28 and the supply 14 a portion 33 of the second heat exchanger 11 is arranged around the first conduit 27, through which cooling medium (refrigerant) can be passed during use, for cooling the second cooling medium.

During use, beverage is fed via the beverage line 6 to the tap 7 to be dispensed thereby. The temperature is measured in the cooling space 10 with the aid of a first temperature sensor 34. If it exceeds a desired temperature, the first heat exchanger 9 will come into operation to supply cold to the cooling space 10 and thereby bring the temperature back to said desired temperature. The second cooling medium is cooled with the aid of the second heat exchanger 11 and pumped through the second cooling circuit C2 through the pump 28. Cold is then exchanged within the jacket 13 with at least the outer wall 35 of the jacket 13 or a part thereof, such that condensation freezes on the outside of the jacket 13 and an ice layer forms. A second temperature sensor 36, for example in the vessel 30, will measure the temperature of the recycled second cooling medium 32. From this, it is possible to determine, with the aid of a control device 37, how much heat is supplied to the second cooling medium 32 in the jacket 13, on the basis of which the temperature of the second cooling medium 32 can be adjusted by means of the second heat exchanger 11.

The temperature of the second cooling medium 32 will be considerably lower than that of the first cooling medium with which the cooling space 10 is cooled and / or the temperature of the cooling space 10 and in particular containers 5 contained therein and beverage contained therein will be considerably higher then that of the second cooling medium 32 in the space 26. By passing air with the aid of the fan 25 through the space 24 along at least a part of the beverage line 6 within the jacket 10, it can be controlled that the temperature of the beverage line 6 or at least beverage therein is kept above the freezing point of the beverage, also when the beverage is stationary in the relevant part of the beverage line 6, while the temperature of the second cooling medium 32 and in particular of the jacket 13 can be kept (considerably) lower. Without wishing to be bound by any theory, the air appears to be used to at least partially heat the beverage line 6, so that the beverage is prevented from freezing, while the jacket 13 and in particular the outer wall as a whole or parts thereof can be cooled such that ice formation can occur thereon and / or an ice layer formed thereon can be maintained. Moreover, in a more general sense, a temperature difference between the cooling space 10, the beverage line 6 within the jacket 13 and the jacket 13 and / or the outer wall thereof can be achieved.

FIG. 4 shows diagrammatically in perspective view a part of a cooling device with tapping column 3, in particular an extra-cooled tapping column 3A, and a part of the cooling circuit C2. The pump 28 is herein provided directly on a bottom side of the vessel 30, which vessel 30 has a closed lid 39. The vessel 30 forms a buffer, so that the temperature control is sufficiently constant and reliable and a sufficient cooling capacity exists. A conduit 40 is shown, which extends from the cooling space 10 to the passage 16 and can bring air from the cooling space 10 into the passage 16 or can discharge it therefrom to the cooling space 10. In fact, this air conduit 40 forms part of the passage 16 as shown in FIG. 3.

FIG. 5 shows in exploded view a part of the tapping device 1, in particular the tapping column 3 and a part of the lines for connecting it. The tapping column 3 with the casing 13 is provided at a lower end 18 with connections for the passage 16 and the supply 14 and discharge 15. A first connector 41 is provided for cooperation with the connections 10 of the tapping column 3. A second connector 42 is provided which can fit into an opening 43 in the top of the cooling space 10, which is, for example, formed by or accommodated in a refrigerator. A connection box 44 is provided on the underside of the second connector 42. The connection box 44 is provided with a first opening 45 for connecting the air line 40 and a second opening 46 for feeding in and / or passing through the at least one beverage line 6 ( not shown in FIG. 5). At the top, the connection box 44 is provided with a connection for a lead-through tube 18 that forms part of or can connect to the passage 16, via the first connector 41. The first line 27 and third line 31 are guided along the lead-through tube 18.

An insulation tube 47 can be arranged around the lead-through tube 46 and the two pipes 27 and 31. In the example shown, the lead-through tube 18 and the lines 27, 31 are slightly curved, in particular somewhat S-shaped. As a result, the tapping column 3 can be arranged displaced relative to the opening 43 and a greater freedom is obtained for placement thereof on a tapping sheet. In one embodiment, the lead-through tube 46 and the lines 27, 31 can be somewhat flexible for even greater freedom of placement.

FIG. 6 shows an exploded view of an embodiment of a tapping device 1, with various tapping columns 3 that can be used thereby. In this embodiment the cooling device is provided with at least three compartments. A first compartment 48 forms the cooling space 10. A second compartment 49 comprises technical elements 50 of the compression in the direction, in particular at least a compressor, a condenser and a fan. Moreover, electronic elements such as the control device 37 can be provided therein. The third compartment 54 can comprise at least the vessel 30, with the pump 28. The second compartment 49 and third compartment 54 are arranged one above the other and can be closed by a plate 55. The first compartment 48 can additionally be provided and be lockable with a door 56. The third compartment 54 is preferably thermally insulated, for example by, among other things, a plate 57. In the intermediate wall 59 between the first compartment 48 and the second compartment 49, an opening 60 is provided for passage of air cooled by the first heat exchanger 9 to the cooling space 10. Optionally, the intermediate wall 59 can act as an evaporator of the first heat exchanger 9. In the cooling space 10, a cooling element 61 can be provided in which, for example, water or drink can be cooled. The cooling element 61 may, for example, comprise a line or channel 6 IA between an inlet 62 and an outlet 63, to which lines (not shown) can be connected, which can extend beyond the cooling space 20. Water can thereby be introduced into the cooling element 61, cooled therein by heat exchange with the air and / or a wall in the cooling space 10 and subsequently released again. In an alternative embodiment, the cooling element can also be designed differently, for example as a bag, vessel, cask or the like. The cooling element 61 is preferably not placed against the coldest wall of the cooling space 10 in order to prevent freezing thereof. More in particular, it is advantageous to place the cooling element 61 against a least cold wall, for example the wall opposite the partition wall or at least opposite an inlet of cooled air.

In an embodiment shown in Fig. 3A, around a part of the beverage line 6 within a tap column 3, for instance the extra cooled tap column 3A, a heating element 70 is arranged, connected to the control device 37. Thereby heat can be supplied to the beverage line and therewith to beverage therein when the temperature of the beverage line and / or the beverage falls below a desired temperature. Such a decrease can for instance be determined on the basis of the change in temperature of coolant in the first and / or second heat exchanger 9, 11, in the cooling space 10 and / or by direct measurement of the temperature of the beverage line 6. Such arrangements will be immediately clear to the skilled person.

Fig. 3B shows a further alternative embodiment, in which the circuit C2 extends substantially as a conduit 26A through the tapping column 3A, wherein a limited space or chamber 26 can be provided. A side of, for example, a thermoelectric element such as a peltier element 80 or the like active cooling element can be arranged against a wall of that chamber or directly against the conduit 26A, while the opposite side of the peltier element, for example, against a side of the wall of the jacket 13. An element to be cooled, such as, for example, a logo L, may be provided against it. Because a greater temperature difference ΔΤ is thereby obtained between element L to be cooled and the heat-emitting side of the peltier element 80, a strong cooling of the element L is obtained in an energetically effective manner, for example for freezing thereof. Moreover, a partial freezing can easily be obtained in this way.

FIG. 7 shows an embodiment of a cooling circuit C, or at least one refrigerant side part thereof. In this cooling circuit C the first heat exchanger 9 and the second heat exchanger 11 are clearly visible, connected in series and coupled via a pipe part 64. Coupled to the second heat exchanger 11 are the vessel 30 and the pump 28. The tapping column 13 is only schematic. in the form of a circle. In the first conduit 27 and the third conduit 31, a first coupling 65 and a second coupling 66 are provided, respectively, for coupling the circuit C2 with the heat exchanger 11. As a result, the circuit C2 can be disconnected and, for example, omitted if no additional cooled tapping column 3A is used, or if another object to be cooled is to be switched on. The tapping device can hereby be constructed flexibly and, if necessary, be designed differently over time. In Fig. 7, a cooling coil 67 is included in the vessel 30, which coil is connected to or integrated in a conduit 68 which can extend from a beverage container 5A into a dispensing column 3, in particular a normal dispensing column 3B.

The circuit C is partly included in the cooling device 2 and partly outside the cooling device 2 or in open communication with the atmosphere outside the cooling device 2. The circuit C comprises an accumulator 69 and a compressor 70. In addition, a condenser 71 (capacitor) and a capillary 72. An evaporator 73 is included in circuit C of the first heat exchanger 9, and an evaporator 74 of the second heat exchanger. It is clearly visible that for the two heat exchangers 9, 11 only one compressor 70, one accumulator 69, one condenser 71 and one capillary 72. This makes the device relatively simple and inexpensive. The compressor 70 can be of modulating design, so that it can be controlled on the basis of, for example, the cold demand in the cooling space, for which the first heat exchanger 9 can be provided, and / or the cold demand of the second heat exchanger and / or a connected to it. cooling object such as the tap column 3A, 3B.

Fig. 8 shows a cooling circuit C, wherein the first heat exchanger 9 and the second heat exchanger 11 are connected in parallel between the capillary 72 and the accumulator 69. Here, the first 9 and the second heat exchanger 11 can be driven together. The 14 y refrigerant in the cooling circuit C will be distributed over the first heat exchanger 9 and the second heat exchanger 11, for example on the basis of the flow resistance of the evaporators 73, 74 of the two heat exchangers 9, 11. In an embodiment not shown 5, a control valve may be included, in flow direction before or behind at least one of the two heat exchangers 9, 11 and preferably in front of or behind both heat exchangers 9, 11, so that the distribution of the refrigerant over the two heat exchangers can be controlled, e.g. based on the cold demand of the two heat exchangers 9, 11. For this purpose, for example, a valve controlled by a temperature sensor can be used. Such a sensor can, for example, be accommodated in the cooling space 10 and / or in or at the dispensing column 3A, 3B and / or in or at the vessel 30.

In addition, the compressor 70 can be controlled on the basis of the temperatures.

Fig. 9 shows a further embodiment of a part of a cooling device with a cooling circuit C, wherein two separate circuits Ci, Cr are shown. In the subcircuit Cr shown on the right-hand side in Fig. 9 a first compressor 70A, a first condenser 7A, a first capillary 72 and the evaporator 73 of the first heat exchanger 9 are included. In the subcircuit Ci shown on the left-hand side, a second compressor 70B, a second condenser 71B, a second capillary 72B and the evaporator 74 of the second heat exchanger 11 are included. In one embodiment the first and second condenser 7A1, B can be accommodated in a housing or be combined as a condenser. In an embodiment with two compressors the advantage can be achieved that the two subcircuits Ci, Cr can be controlled at least partially and preferably entirely independently of each other, wherein the control is relatively simple and can be arranged on the basis of separate temperature sensors for the both subcircuits.

Fig. 10 schematically shows two tapping columns 3A, 3B coupled to the same cooling circuit, for example the cooling circuit C2 of the second heat exchanger. The two tapping columns 3A, 3B are connected to the buffer vessel, wherein a distribution over the two tapping columns is provided. A throttling device 81 is included in the flow direction before and / or after one of the tapping columns 3A, whereby a preselected distribution of the cooling liquid over the two tapping columns 3 can be obtained and thereby cooling thereof. In an alternative embodiment, the two tapping columns 3A, 3B can be included in series in the circuit C2. Preferably, the extra cooled tap column 3A is included in the direction of flow of the cooling liquid for the other tap column 3B. The tapping columns 3A, 3B can for instance be interpreted such that ice forms on the casing or part thereof of the first tapping column 3A, while the second tapping column 3B or at least one beverage line extending therein are cooled only without freezing occurring. To that end, a throttling device may optionally be provided between the tapping columns 3A, B.
